Absolutely!! Don't deprive yourself of an opportunity to shoot and enjoy the sport. There may be a chance that the SO is simply ignorant of the rules, and "doesn't know what he doesn't know". If he is any type of a sportsman and fair of mind, he should be receptive to input and questions . Unless he is the ONLY authority in this particular club when it comes to fairly administering rules for the benefit of fairness to all competitors, there should be someone (or several someones) who will listen to a legitimate, clearly stated complaint and be willing to get this straightened out.
You have every right to seek answers to your questions about rules and to speak up if they are being administered incorrectly or unfairly.
Good luck!

If the stage description called for three shots to the body and two shots to the head and three were in the body and the other two were in the not in the head box, then the target should be scored "Down 10". (That's assuming all three shots in the body were in the "0" box of the body).
Your score keeper is mistaken and if he continues to use this approach to scoring, will discourage shooters from participating in the sport.

The Blade Tech holster (https://blade-tech.com/products/classic-owb) and double magazine carrier (https://blade-tech.com/products/signature-series-double-mag-pouch), paired with a Wilderness belt (http://www.thewilderness.com/belts/original-instructor-belt/) is a great setup. About anything, including a large shirt will work for a cover garment, but a stiffer and heavier vest similar to the 5.11 vest (https://www.511tactical.com/taclite-pro-vest.html?utm_medium=cpc&amp;utm_source=google&amp;utm_term=5.11+tactical+men's+taclite+pro+vest+(khaki%2ftan)&amp;utm_content=ap) is easier to clear away from the holster when you draw (at least for me, it is).

If you are looking for aggressive LOK grips, goes with the Bogies. For a less aggressive LOK grip, try the Matrix model. I like the thin Bogies on my competition CZ's and the thin Matrix gips on my carry pistol.

I like the 124 gr. bullets over 4.0 to 4.2 of Titegroup for the 9mm. COAL adjusted to meet what your pistol likes for the profile of bullet you have chosen. Montana Gold JHP's are my personal favorite.

And I have three pistols built by CZC and one by CGW and haven't a single complaint about any of them. I live very near CZC and they are extremely helpful and responsive to any questions I have posed to them. CZC is currently building another pistol for me (a CZ 97B).
